Market growth for calcined petrol coke is accelerating due to an increase in steel consumption. The low price of calcined petrol coke and its high yield make it a great alternative to coal.
A by-product from oil refineries, green petroleum coal, or petcoke as it is commonly known, is produced. The coke is produced to make carbon anodes in the aluminum and steel industries, as well as graphite electrodes.
It is produced by the oil refinery process and contains a lot of carbon. This is the result of heating crude oil to high temperatures, which breaks down hydrocarbons. It is a solid that can be used to make a number of products.
Oil coke is an excellent fuel source for power plants because of its low ash level and high content in carbon. The coke is used in the production of cement, and metal smelting.
Petcoke's quality depends on the refinement process and its source. Green coke, which is coke straight from the coker, requires further processing in a rotary oven, called calcining. This process removes any volatile material and increases the amount of carbon fixed.
The production of graphite electrodes for aluminium smelting often uses calcined PETCOKE. The low levels of impurities, the availability and relative low costs are reasons for its popularity. This metal is highly resistant to both physical and chemcial degradation.
Oil refining produces petroleum coke as a waste product. As crude oil is refined to produce gasoline and other fuels, some of the heavier hydrocarbon molecules are broken down through a process called delayed coking. A solid carbon substance called coke is created. It can then be classified into two petcoke types: anode and fuel grade. Fuel grade petcoke can be burned to produce steam and electricity in boilers, whereas anode-grade coke is used in the aluminum smelting process for carbon anodes.
Petcoke is a raw material that can emit gaseous or particulate pollutants when it's handled and stored. The study assessed exposure levels at two sites, upwind and downstream of a petroleum-coke calciner. It used modeled air pollution standards and benchmarks for public health. The results of the study revealed that the emission levels from a properly run calciner are not unreasonable for human health. Demand for calcined Petcoke is driven primarily by the growth of iron and steel, cement production and electricity generation.
Calcined petroleum coal (CPC) can be produced as a carbon-rich material by heating petroleum coke in order to evaporate moisture and volatile materials. The resulting calcined coke is used in several metal production processes, including aluminum production and steel processing. This coke also has a much lower electrical resistance compared to coal. It is useful for the industries that use graphite as electrodes.
The molecular structure of raw materials such as carbon is altered during the calcination to increase the material’s physical characteristics. During the calcination process, the volatile matter in carbon raw materials is eliminated and the molecular structure changes to improve the physical properties of the product. In addition, calcination reduces the secondary shrinkage of the raw material and helps to stabilize the product.
It is used primarily in aluminum production. It can increase the conductivity in aluminum, and also reduce the energy used during the melting. It's also used to make titanium dioxide, and to recarburize steel.
Petcoke is tested to ensure that its carbon content meets industry standards and that it has other important qualities such as low metal and sulfur concentrations. This is done to protect the environment as well industrial equipment. Tests also help ensure that emissions generated by calcining remain below acceptable levels in terms of human and environmental health.
Its characteristics determine the many uses that can be made from calcined petrol coke. In the production of aluminum, calcined petrol coke is used to make electrodes. The production of cement also uses calcined coke as a low-ash, high-energy alternative to coal. For industrial boilers, fuel grade calcined Petroleum Coke provides steam and heating for different processes.
Inhaling petcoke particles that have been pulverized can lead to respiratory irritation and even lung disease, like COPD. However, exposure to pulverized petcoke is less harmful than exposure to particulate matter from burning fossil fuels like coal. In vivo tests of carcinogenicity have also shown that petcoke does not increase cancer risks.
